IMPROVEMENT IN RUFFLING ATTACHMENTS FO'R'SEWING-MACHINES.

Specification forming part of Letters Patent No. 168,141, datedSeptember 28, 1875; application filed I August 13, 1875.

To allv whom it may concern:

Be it, known that I, WILBER H. GONVERS, of the city of New Orleans,Orleans'parish, State of Louisiana, have invented new and usefulImprovements in Rufflin g Attachments for Sewing-Machines, of which thefollowing is a full description, reference being had 330 theaccompanying drawings, in which- Figure l is a side elevation; Fig.2, ato view; and Figs. 3, 4:, and'5, details.

The device is designed to be attached to the presser-foot of asewing-machine. Its construction is, in many respects, similar to thatof other rufflers in use; but the parts are so arranged that the mainportion of the device is behind instead of forward of the presserfootbar; and the invention consists in this.

arrangement of parts-in hinging the rufflingbar to the other portion ofthe device, and in the devices for adjusting the movement of theruffling or crimping plate.

In the drawings, a b represent a presserfoot, to be attached to thepresser-foot bar, as usual. 0 is a socket, permanently attached to a. dis a slot in the side of the socket 0. e is a sliding plate, which movesin the socket 0. Its rear end is bent around, as shown at c, Fig. 2. fis a pin secured to the plate 0, and moving in the slot cl. g is alever, pivoted at h to I the socket 0, having an eye at one end, adaptedto receive the pin on the needle-bar, as usual. lais an extension on therear end of the lever g, in which is a slot, '0,- which passes over thepin f. Ateach end of this extension is are cars provided withscrew-threaded holes, to receive the adjusting-screws 4; i. m is the barwhich carries the crimping or ruffling plate a, which is located beneaththe presser-foot bar. m is hinged at its rear end to the extension 6' ofthe sliding plate e-by means of a pin, a, and

the pin it, upon which it is hinged, passes through the rear end of themain portion of the plate 0. (See Fig. 2.) Around this pin n is a coileda spring, 8, havingits ends extended.

" One end comes in contact with the inside of e,

andthe other in contact with an extension, 1", from the rear end of m.

In use the crimping-plate u is operated by means of the lever g, asusual. The distance which the crimping-plate u moves with each movementof the needle-bar can be adjusted by means of the screw 2', the innerend of which comes in contact with the pin f. It is important that thecrimping-plate u, at each movement, be carried back, so as to bring thecrimped cloth back of the point of the needle, and unless there is asuitable adjusting device this result will not be accomplished'properlyafter the parts become somewhat worn by use. I provide for thisadjustment by means of the screw 43, by means of which, as the partswear, the movement of the crimper toward the needle can be adjusted.

I find that there is an advantage in hinging the bar m, which carriesthe crimping-plate, at its rear end, and holding it down by means of thespring 8, this hinging giving freedom of movement, and allowing thecrimping-plate to adapt itself to different thicknesses and conditionsof cloth.

It will be observed that the rear portion of the device is in the rearof the presser-foot and at some distance above the cloth-line. Thisarrangement is desirable, as it allows the operator to readily watch thework, and the-- instrument being less liable to interfere with themovement of the cloth. 7

What I claim as new, and desire to secure by Letters Patent, is asfollows 1. In a ruffler, the hinged bar m, provided with the plate a, incombination with the sliding bar 0 and spring s, substantially asdescribed.

2. The combination of the socket a, sliding bar 6, hinged bar m,operating-lever g, and presser-foot a b, substantially as and for thepurpose specified.

3. In a ruffler, the lever g k, screws M, socket c, sliding plate 6, andpin f, all construeted and operating substantially as specified.
